I agree 100% (even if we can not fully understand how) that “but all creation and all the actions of men, including the fall are for His glory”
I’ll go even further and state I agree with the teaching that Earth was actually created by and for Christ. Such teaching makes it clear that the Incarnation was God’s will from the begining.
I’ll have to check the sources for the statement about the envy of the rebel angels. It is an ancient one and fits well with their pride and their hatred of us.
Please do..I have heard that the angelic creation then rebellion occurred at different times in relation to the creation of the earth.. not essential information ..but an interesting contemplation.
I have heard also that the angels watch us to learn more about God and that the fallen angels are jealous because there is no salvation for them ...
